Custom CSS-Applying selected background for all the cols in the report

Question

Hi,
I am trying to set a particular background for all the columns in the report(not for all the projects,so that I can avoid option of manually setting background color for complete report.For this I thought custom CSS is best option.So edited custom.css(C:\OBI11g_Middleware\Oracle_BI1\bifoundation\web\app\res\s_blafp\b_mozilla_4) file with below code and went to the Answers-> Criteria->Choose Column->style-> check "Use Custom CSS Class"->MyCell
Code used in custom.css
.MyCell { background-color: #00ff00; font-style:italic; font-weight: bold;}
Somehow I dont see the background color applied to any of the columns in report.Can anyone had successful attempt of this Custom CSS.Thanks in Advance.

I am trying both the solutions.
User 979493,
I started manually writing the code instead of pasting and almost worked.In the mentioned below paths I dont have custom.css file,so I created one and manually entered below code.But does it work for only that particular column and not for all the columns.Is it supposed to work for all the columns or just that column.
For example: I have 2 cols in the report,I used "Use Custom CSS Class" -> MyCell for the first column and when I ran results it shows background color for only col1 and not for col2.I thought this feature will apply background color for all the columns in the report.Please correct me if I am wrong.
custom.css file content:
.MyCell{background-color: #00ff00;font-style:italic;font-weight:bold;}
